Hello,
I'm playing around a bit with electron-flow arrows in Marvin 6.1.3. I notice that electron-flow arrows cannot begin at atoms now; instead, they must begin at lone pairs. That's OK; but now when I mouse over an atom with the two-electron arrow tool, a bond from that atom to one of its ligands is highlighted, which is confusing. It would be much better either for nothing at all to be highlighted when one mouses over an atom, or for one of the lone pairs on the atom to be highlighted.
I also notice that when I load an MRV into Marvin that doesn't have the new format for lone pairs, then add an electron-flow arrow, then press the Undo button, the lone pairs disappear. If I press the electron-flow arrow button again or mouse over the canvas, the lone pairs reappear. Very minor bug, but disconcerting.
